A small part of downtown Chicago in the winter

Chicago has a climate typical of the U.S. Midwest. Sudden changes of weather, large daily temperature ranges, and unpredictable precipitation patterns are all staples of Chicago weather. Chicago has four clearly defined seasons, although in certain years some seasons may overextend their welcome and linger into months they do not traditionally occupy. For example, in Chicago it has snowed in September (1942), been 90°F (33°C) in March (1982), and had a day where the high and low temperatures differed by more than 65°F (31°C) in one day (February 8, 1900).
